Upon reflection: What was tried clearly did not work. How would you actually do things differently given the knowledge that the actually occurring history we are discussing did not succeed in solving the problem. I am willing to be convinced a different approach is better, but I am very unlikely to be convinced what was tried was the optimal solution. I am advocating a cauterization approach because if it did go far enough, going all the way would be a good second attempt. If it works by going too far, at least it worked and nothing else has.
